摘要： A latch body for use in a drilling head assembly including a fluid control subassembly, a check valve element, and/or a hollow spindle. A distal end portion of the latch body includes a port section that defines a chamber for receiving the check valve element and promoting movement of the check valve element between a blocking position and an open position. The hollow spindle of the fluid control subassembly is operatively coupled to the chamber of the port section and supports the check valve element in the blocking position. A proximal end portion of the latch body supports the fluid control subassembly of the drilling head assembly in an operative position. The latch body includes male protrusions extending inwardly toward and spaced from a longitudinal axis of the latch body. A plurality of channels extend radially outwardly from the longitudinal axis of the latch body, spanning between adjacent male protrusions.

摘要： Implementations of the present invention include a core barrel assembly having a driven latch mechanism. The driven latch mechanism can lock the core barrel assembly axially and rotationally relative to a drill string. The driven latch mechanism can include a plurality of wedge members positioned on a plurality of driving surfaces. Rotation of the drill string can cause the plurality of wedge members to wedge between an inner diameter of the drill string and the plurality of driving surfaces, thereby rotationally locking the core barrel assembly relative to the drill string. Implementations of the present invention also include drilling systems including such driven latch mechanisms, and methods of retrieving a core sample using such drilling systems.
